Matt sighs, hmmm. The lighter kisses draw a sort of attentive flutter, palpable in the change to his heartbeat and shifting of his muscles. At the harder ones, his legs move fitfully, lips rounding on an oh. His hands scrub up Obi-Wan's side, his arm, before he remembers--

"I'm not gonna hurt anything. Am I?"

As his fingers gentle, tracing the path of a scar.
